LAGKNER, or ,ozoNE PARK, NEW YORK, ssI NOR T LAGKNER rn'onuc'rs CORPORATION, OF BROOKLYN, NEW YORK, A OOEPORArION or DELAWARE COMBINED LIGHT GLOBE AND TRAFFIC SIGNAL Application filed April 5,

This invention relates to a combined street light and trafiic signal, and one object of the invention is to provide a globe which'may be applied to an overhead street light and serve to permit a street tobe well illuminated as well as constituting a. traflic signal.

rected downwardly at an incline and thereby prevented from shining directlyqin the eyes of a person driving an automobile along a street. I

Another object of the invention is to provide'theglobewith side extensions against which lenses formed separate from the globe may be secured by cement and firmly held in' lace without danger of theglobe or lenses ing broken by expansion and contraction during heating and cooling of the globe and lenses when in use.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a View showing the improved street light and traflic signal in side elevation; v

Fig. 2 is a top plan view of the same;

Fig. 3 is an enlarged sectional view through the improved globe, and

Fig. 4 is a sectional view through a globe illustrating .the manner of forming the globe and applymg the lenses to the same.

The post or standard 1 may be of any height desired and is to be erected in a vertical position either in the center of a street crossing or upona sidewak sufiiciently close to the curb to permit the combined lights and signals carried thereby to be easily seen by a person driving an automobile along a street. Arms 2 extend from adjacent the upper end of the post and areprovided with depending 1928. Serial no; 267,620.

end portions 3 carrying lamps 4 which are preferably electric lamps of a conventional construction. Each lamp is provided with the usual socket to carry a bulb 5 and iii-- cludes a hood 6 to which a globe is to be connected, and it will be'understood that when a globe is connected with the hood it will enclose the bulb. The globes are indicated in general by the numeral 7 and each carries lenses 8 which project from its sides and are so spaced from each other aboutthe globe that pairs of lenses are disposed in opposed relation to each other, as shown in Fig. 2. If the light and signal is erected at a street intersection, oneset of opposed lenses of each globe will be preferably green and the other set red but the red and green lenses of one globe will be at right angles to the corresponding lenses of the other globe. Therefore, when one lamp is illuminated, it will indicate that traflic is to proceed in one direction across the street intersection and when the light of the other globe is illuminated, it will indicate that the reverse movement of traflic is totake place. The arms 2 which'is formed of glass of a translucent.

nature so that light may pass through it but at the same time the globe serves to prevent the bulb from being directly seen and the driver of an automobile blinded by a bright light. This globe is substantially spherical in its outline, as clearly shown in Figs. 1 and 2, and is formed with an upstanding open neck 1O- adapted to be fitted into the hood 6' and secured therein in a conventional manner. The upper portion of the globe about the neck is unbroken and the lower portion also constitutes a segment of a sphere and is preferably formed with a depending nipple 11. Between its upper and lower portions the globe is formed with side extensions 12 formed in opposed relation to each other and when the globe is originally molded each of the side extensions is provided with. a portion extend diagonally, as shown in 'Fig. 2, so that i 13 of a reduced diameter leading from an annular shoulder or flange 14 and closed at its outer end by a head 15 which extends inwardly, as shown in Fig. 4.. If the globe is to be used in connection with a light serving merely to illuminate a street, it is employed in the condition in which it is removed from its mold or, in other words, each side extension remains in the form shown at the left of Fig. 4, but if the globe is to serve as a trailic signal, one or more lenses will be applied, as shown in Figs. 1, 2 and 3. If the signal is employed at a street intersection, lenses will be applied to all of the side extensions and they may be of different colors, such as red and green, or any other color desired,

such as yellow, to indicate a dangerous crossing. If the signal is erected at the end ofa street or where a street is interrupted by a park, only one lens is needed and this will preferably be red to indicate danger or the end of a street.

When a lens is to be applied to a globe, the reduced portion ofthe side extension to which it is to be applied is removed substantially even with the bordering shoulder or flange 14 and the outer surface of the shoulder and any remaining portions of the reduced extension are ground so that an uninterrupted outer surface will be provided. This surface will be roughened during the grinding process so that when cement is applied to it it will firmly adhere to the flange. The lens is slightly smaller in diameter than the external diameter of the flange and when cement is applied to the marginal portions of the lens or outer surface of the flange and the lens set in place the cement when dry will serve to very securely retain thelens in engage ment with the globe. The globes are initially molded with the extensions so that when they are to be used the lenses may be applied or not according to the particular use to which the globe is to be put. From an inspec'tion of Fig. 3, it will be readily seen that when the globe is in place the bulb 5 terminates above the centers of the lenses and, therefore, light rays emitted by the bulb will pass outwardly through the lenses at a downward incline, and in the preferred arrangement will strike the pavement about a hundred feet from the post. Therefore, the light passing through the lenses will not glare in the eyes of a person driving an automobile along a street.

Having thus described the invention, I claim:

1. In a combined street light and si al, a globe of light penetrable material a apted to be connected with a light carrier in enclosing relation to a light carried thereby and having its intermediate portion formed with a hollow side extension projecting outwardly therefrom and formed with a circumferentially extending shoulder, an opening being formed in the outer end of the extension bordered by the shoulder, and a tinted lens secured against said shoulder in covering relation to the outer end of said extension and constituting an indicator.

2. In a combined street light and signal,

a globe of light penetrable material consisting of a hollow globular body having its in termediate portion formed with hollow outwardly extending side extensions normally closed at their outer ends, flat annular shoulders being provided about the side extensions adjacent their inner ends, one extension being out oflf at its shoulder to provide an opening bordered by a flange, and a lens secured against the flange in covering relation to the opening and constituting an indicator.

3. A method of forming a combined si al and street light globe consisting of 11101 ing a hollow globular body of light penetrable material, the body being formed with a hollow side extension closed at its outer end and reduced in diameter from its outer end to adjacent its inner end to form an outstanding annular shoulder, cutting oflf the side extension flush with the shoulder to provide the body with a side opening bordered by an inwardly extending flange having a roughened face, and disposing a lens in covering relation to the side opening with its marginal portions secured against the outer surface of the flange. v

4:. A method of forming a combined light globe and signal consisting in molding of light penetrable material, a hollow body having a hollow extension at its side, cutting 01f the extension to form an opening through the body, disposinga lens in covering rela tion to the opening, and securing marginal portions of the lens to the body about the opening.

In testimony whereof I aflix my signature.
